Or do jou mean my device isn't representative?
Yes, this. Most devices it just works, and a small minority will work with a little effort. A miniscule number will be like yours. It isn't representative of the average experience. It's an outlier.
Out of curiosity, how long ago was this? It very well may have the support now, though if it's from some manufacturer using proprietary drivers for their webcams, for some crazy stupid reason, then maybe not.
